The invention relates to novel substitutedsulphonylaminocarbonyltriazolinones, to several processes for theirpreparation and to their use as herbicides.

It is already known tat certain sulphonylaminocarbonyltriazolinones,such as4,5-dinethyl-2-(2-chloro-phenylphonyl-aminocarbonyl)-2,4-dihydro-3H-1,2,4-triazol-3-one,exhibit herbicidal properties (cf. EP-A 341 489; cf also EP-A 422 469;EP-A 425 948; EP-A 431 291). However, the effect of these compounds isnot satisfactory in all respects.

The novel sulphonylamiocarbonyltriazolinones of the general formula (I),##STR1## in which Q represents oxygen, sulphur or the grouping--N(R⁴)--,

Q¹ represents --CO-- or --SO₂ --, and

R⁵ represents alkyl, cycloalkyl or aryl which are in each caseoptionally substituted,

and salts of compounds of the formula (I) have now been found

The novel sulphonylaminocarbonyltriazolinones of the formula (I) areobtained if

(a) chlorosulphonylaminocarbonyltriazolinones of the general formula(II) ##STR2## in which R¹ and R² have the abovementioned meaning,

are reacted with nucleophilic compounds of the general formula (III)

    R.sup.3 --Q--H                                             (III)

in which

Q and R³ have the abovementioned meaning,

where appropriate in the presence of an acid acceptor and whereappropriate in the presence of a diluent,

or if

(b) triazolinones of the general formula (IV) ##STR3## in which R¹ andR² have the abovementioned meaning,

are reacted with chlorosulphonyl isocyanate, where appropriate in thepresence of a diluent, and the resultingchlorosulphonylarinocarbonyltriazolinones of the formula(II)--above--are reacted, without intermediate isolation, withnucleophilic compounds of the general formula (III)--above--, whereappropriate in the presence of an acid acceptor and where appropriate inthe presence of a diluent,

and, where appropriate, the compounds of the formula (I) which areobtained by processes (a) or (b) are converted into salts usingcustomary methods.

Further possible methods for preparing the novel compounds of theformula (I) are listed below, with Q, R¹, R² and R³ in each case havingthe abovementioned meaning:

Surprisingly, the novel compounds of the formula (I) exhibit asubstantially more powerful herbicidal effect than structurally similar,known 4,5-dimethyl-2-(2-chlorophenylsulphonyl-aminocarbonyl)-2,4dihydro-3H-1,2,4-triazol-3-one.

The chlorosulphonylaminocarbonyltriazolinones of the general formula(II) have still not been disclosed in the literature; they are thesubject-matter, as novel compounds, of a previous application (cf DE-P4234801/LeA 29398 of 15.10.1992).

The compounds of the formula (II) are obtained if triazolinones of thegeneral formula (IV) ##STR10## in which R¹ and R² have theabovementioned meaning,

are reacted with chlorosulphonyl isocyanate, where appropriate in thepresence of a diluent, such as methylene chloride, at temperatures ofbetween -20° C. and +50° C., and worked up in a customary manner (cf.the preparation examples).

The nucleophilic compounds which are to be used as starting compounds inthe novel processes (a) and (b) for preparing compounds of the formula(I) are defined generally by the formula (III).

In formula (III), Q and R³ preferably or in particular have thosemeanings which have already been indicated above, in connection with thedescription of the novel compounds of the formula (I), as beingespecially or in particular preferred for Q and R³.

The starting compounds of the formula (III) are known organic synthesischemicals.

The triazolinones which are to be used as starting compounds in thenovel processes (a) and (b) for preparing compounds of the formula (I)are defined generally by the formula (IV).

In formula (IV), R¹ and R² preferably or in particular have thosemeanings which have already been indicated above, in connection with thedescription of the novel compounds of the formula (I), as beingespecially or in particular preferred for R¹ and R².

The starting compounds of formula (IV) are known and/or can be preparedby processes which are known per se (cf. EP-A 283876, EP-A 294666, EP-A301946, EP-A 298371, EP-A 341489, EP-A 399294, EP-A 398096, EP-A 422469,EP-A 425948, EP-A 431291, EP-A 477646, DE-A 4110795).

The novel processes (a) and (b) for preparing the novel compounds of theformula (I) are preferably carried out using diluents. In this context,virtually all inert organic solvents are suitable for use as diluents.These solvents preferably include aliphatic and aromatic, optionallyhalogenated hydrocarbons, such as pentane, hexane, heptane, cyclohexane,petroleum ether, benzine, ligroin, benzene, toluene, xylene, methylenechloride, ethylene chloride, chloroform, tetrachloromethane,chlorobenzene and o-dichlorobenzene, ethers, such as diethyl ether anddibutyl ether, glycol dimethyl ether and diglycol dimethyl ether,tetrahydrofuran and dioxane, ketones, such as acetone, methyl ethylketone, methyl isopropyl ketone and methyl isobutyl ketone, esters, suchas methyl acetate and ethyl acetate, nitriles, such as acetonitrile andproprionitrile, amides, such as dimethylformamide, dimethylacetamide andN-methylpyrrolidone, and also dimethylsulphoxide, tetramethylenesulphoneand hexamethylphosphoric triamide.

In the novel processes (a) and (b), all the acid-binding agents whichare customarily usable for reactions of this nature may be employed asacid acceptors. Those which are preferred are alkali metal hydroxides,such as sodium and potassium hydroxide, alkaline earth metal hydroxides,such as calcium hydroxide, alkali metal carbonates and alkali metalalcoholates, such as sodium and potassium carbonate, and sodium andpotassium tert-butoxide, and, in addition, basic nitrogen compounds,such as trimethylamine, triethylamine, tripropylamine, tributylamine,diisobutylamine, dicyclohexylamine, ethyldiisopropylamine,ethyldicyclohexylamine, N,N-dimethylbeneylamine, N,N-dimethyl-aniline,pyridine, 2-methyl-, 3-methyl-, 4methyl-,2,4-dimethyl-, 2,6-dimethyl-,2-ethyl-, 4-ethyl- and 5-ethyl-2-methyl-pyridine, 1,5-diazabicyclo4.3.0!-non-5-ene (DBN), 1,8-diazabicyclo- 5.4.0!-undec-7-ene (DBU) and1,4-diazabicyclo- 2.2.2!-octane (DABCO).

In the novel processes (a) and (b), the reaction tee s may be variedover a relatively wide range. In general, the processes are carried outat temperatures of between -20° C. and +80° C., preferably attemperatures of between -10° C. and +50° C.

In general, the novel processes (a) and (b) are carried out understandard pressure. However, it is also possible to carry them out underelevated or reduced pressure.

In order to carry out the novel processes (a) and (b), the startingcompounds which are required in each case are in general employed inapproximately equimolar quantities. However, it is also possible to useone of the components which is employed in each case in a relativelylarge excess. In general, the reactions are carried out in a suitablediluent in the presence of an acid acceptor, and the reaction mixture isstirred for several hours at the temperature required in each case. Inthe novel processes (a) and (b), the working-up is in each case effectedusing customary methods (cf the preparation examples).

Where appropriate, salts may be prepared from the novel compounds of thegeneral formula (I). These salts are obtained, in a simple manner, usingcustomary methods for salt formation, for example by dissolving ordispersing a compound of the formula (I) in a suitable solvent such asmethylene chloride, acetone, tert-butyl methyl ether or toluene, andadding a suitable base. The salts can then be isolated--whereappropriate after a relatively long period of stirring--by concentratingor by filtering with suction.

The active compounds according to the invention can be used asdefoliants, desiccants, haulm destroyers and, especially, asweedkillers. By weeds, in the broadest sense, there are to be understoodall plants which grow in locations where they are undesired. Whether thesubstances according to the invention act as total or selectiveherbicides depends essentially on the amount used.

The novel active compounds can be used, for example, in connection withthe following plants:

Dicotyledon weeds of the genera: Sinapis, Lepidium, Galium, Stellaria,Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio,Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum,Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala,Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis,Papaver, Centaurea, Trifolium, Ranunculus and Taraxacum.

Dicotyledon crops of the genera: Gossypium, Glycine, Beta, Daucus,Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana,Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Cucurbita

Monocotyledon weeds of the genera: Echinochloa, Setaria, Panicum,Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus,Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis,Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea,Dactyloctenium, Agrostis, Alopecurus and Apera

Monocotyledon crops of the genera: Oryza, Zea, Triticum, Hordeum, Avena,Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.

However, the use of the active compounds according to the invention isin no way restricted to these genera, but also extends in the samemanner to other plants.

Depending on the concentration, the compounds are suitable for totalweed control, for example on industrial terrain and rail tracks, and onpaths and areas with or without tree stands. Equally, the compounds canbe employed for controlling weeds in perennial crops, for exampleforests, ornamental tree plantings, fruit orchards, vineyards, citrusgroves, nut orchards, banana plantations, coffee plantations, teaplantations, rubber plantations, oil palm plantations, cocoaplantations, soft fruit plantings and hopfields, in lawns, turf andpastures, and for selective weed control in annual crops.

The novel compounds of the formula (I) are particularly suitable forselectively controlling monocotyledonous and dicotyledonous weeds inmonocotyledonous cultures both in the pre-emergence and in thepost-emergence processes.

In addition to this, the novel active compounds (I) also exhibitinteresting side effects, namely a foliar insecticidal effect andfungicidal effects, in particular against Pyricularia oryzae and againstErysiphe graminis.

The active compounds can be converted into the customary formulations,such as solutions, emulsions, wettable powders, suspensions, powders,dusts, pastes, soluble powders, granules, suspoemulsion concentrates,natural and synthetic materials impregnated with active compound, andmicroencapsulations in polymeric substances.

These formulations are produced in a known manner, for example by mixingthe active compounds with extenders, that is liquid solvents and/orsolid carriers, optionally with the use of surfactants, that isemulsifiers and/or dispersants and/or foam-formers.

If water is used as an extender, organic solvents can, for example, alsobe used as auxiliary solvents. Liquid solvents which are suitable aremainly: aromatics such as xylene, toluene or alkylnaphthalenes,chlorinated aromatics and chlorinated aliphatic hydrocarbons such aschlorobenzenes, chloroethylenes or methylene chloride, aliphatichydrocarbons such as cyclohexane or paraffis, for example petroleumfractions, mineral and vegetable oils, alcohols such as butanol orglycol as well as their ethers and esters, ketones such as acetone,methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, stronglypolar solvents such as dimethylformamide and dimethyl sulphoxide, andwater.

Suitable solid carriers are:

for example ammonium salts and ground aural minerals such as kaolins,clays, talc, chalk quartz, attapulgite, montmorillonite or diatomaceousearth, and ground synthetic minerals such as highly disperse silica,alumina and silicates; suitable solid carriers for granules are: forexample crushed and fractionated natural rocks such as calcite, marble,pumice, sepiolite and dolomite, or else synthetic granules of inorganicand organic meals, and granules of organic material such as sawdust,coconut shells, maize cobs and tobacco stalks; suitable emulsifiersand/or foam-formers are: for example non-ionic and anionic emulsifiers,such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcoholethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkylsulphates, arylsulphonates and protein hydrolyzates; suitabledispersants are: for example lignin-sulphite waste liquors andmethylcellulose.
